The thing is that after building i cant find NotesGwtApp.gwt.xml file :)
There are 2 pictures for better understanding. What is going on?
I really dont understand why is that...

Answer 1

The behavior you're seeing is standard for Maven. It is because Maven, by default, only looks for .java files in the src/main/java folder, while some tools might include all files by default, and hence the confusion.
You need to tell Maven that you also have non-java resources in your src/main/java folder; you might want to add a piece of config such as:
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*</include>
</includes>
<excludes>
<exclude>**/*.java</exclude>
</excludes>
</resource>
</resources>
